Fantina

"Ohohoho!! Finally, you have arrived! Since I came to this country, always I try to learn new things. They hold Contests in this city? I say to myself, enfin, I will excel. That is why I dress this way. C'est une performance! Also, I study Pokémon very much. I have come to be Gym Leader. And, uh, so it shall be that you challenge me. But I shall win. That is what a Gym Leader does, non?"

- Fantina

Fantina (メリッサ) is the Gym Leader of Hearthome City. She specializes in Ghost-types. She gives the Relic Badge to Trainers who defeat her.

Platinum Nuzlocke
Fantina was talking with Johanna in the Hearthome City Contest Hall when Johanna's son RYFUBA walked in. Fantina asked RYFUBA if he was there to participate in the Contest. As soon as RYFUBA told her yes, Fantina told him that she was waiting for him at the Gym before departing.

After RYFUBA placed second in the Contest and evolved RAISIN into an Empoleon, RYFUBA challenged Fantina to a Gym battle. RYFUBA proceeded to easily defeat Fantina's entire team, even her Mismagius, with only RAISIN. Defeated, Fantina gave RYFUBA the Relic Badge.

Trivia

 * Fantina's name is possibly a phonetic pun on the word phantom, alluding to her usage of Ghost-type Pokémon. Her name also has the Italian diminutive feminine ending -ina, alluding to the fact that she is foreign.
